Truex turned a lap at 135.120 m.p.h. (26.643 seconds) for his third pole of the season and the fourth of his Sprint Cup Series career. He won the pole for the season-opening Daytona 500 and the fall night-time race at Atlanta earlier this year.

"It was a good lap for us," Truex said. "We only made two qualifying runs during practice, and I felt like our last one we kind of went the wrong direction. So we had a good idea of what we needed to do to get a good lap in qualifying. Obviously we didn't know it would be that good."

On Tuesday, Truex was docked 50 points and crew chief Kevin Manion received a $50,000 fine after his No.1 Chevrolet failed post-race inspection last Sunday at Texas Motor Speedway. NASCAR officials discovered the front of Truex's car was too low and therefore did not meet the required height specification.

Truex, currently 26th in points, will make his second-to-last start for Earnhardt-Ganassi Racing at Phoenix. The 29-year-old driver will head to Michael Waltrip Racing for the 2010 Sprint Cup campaign.

Kurt Busch, who won at Texas, qualified on the outside pole with a lap at 134.579 m.p.h.

"It was a good surprising lap for us, but it was a little on the loose side," Busch said. "Some of the momentum from last week carried over, and we're just trying to hit our marks and put ourselves in great position."

Busch's crew chief, Pat Tryson, is leaving Penske Racing at the end of the season to guide Truex's efforts at MWR next year.

Jimmie Johnson will start third, as he looks to rebound from his disappointing 38th-place finish at Texas. Johnson, attempting to win his unprecedented fourth straight Cup championship, crashed in the opening laps at Texas and saw his points lead shrink to 73 over Hendrick Motorsports teammate Mark Martin.

"Hopefully we're far enough forward to avoid any early issues in the race if there are any," Johnson said. "It felt really good to put down a really strong lap based on the week and thinking about Texas and what took place there with loosing all the points."

Johnson has won three of the last four races at Phoenix, including the last two fall events here.

Kasey Kahne qualified fourth, while Denny Hamlin took the fifth spot.

Greg Biffle, Kyle Busch, Tony Stewart, Casey Mears and Martin completed the top-10. Martin won the spring race at Phoenix in April.

"[The car] was just all over the place," Martin said. "I needed a breathtakingly spectacular lap, but I got a below average lap."

Jeff Gordon, currently third in points (-112), will start 14th.

Regan Smith, Kevin Conway and Brandon Ash failed to qualify.

Sunday's race is scheduled to start just after 3:15 p.m. (et).
